Free Online Hardware Tests

What hardware can I test on this website?

You can test displays (dead pixels, refresh rate, HDR, flicker, color depth, brightness, black levels), keyboards (all keys, rollover, typing speed), mice (DPI, polling rate, double-click, scroll speed), audio devices (microphone, hearing range, bass, headphones, speaker channels), gaming performance (reaction time, FPS, aim training, input lag), controllers (Xbox, Switch, PS5), touchscreens, stylus pens, and system performance (RAM, CPU, browser benchmark, network latency). 50+ tools are available, all free and browser-based.

Do I need to download any software?

No, all tests run directly in your browser using standard Web APIs. There is no installation, no account registration, and no software to download. Simply open the tool in any modern browser and start testing immediately. This works on Chrome, Firefox, Edge, and Safari across Windows, macOS, Linux, Android, and iOS.

Is this website free to use?

Yes, HardwareTest is free to use with no account requirement and no software download. The site may be supported by advertising, affiliate links, sponsorships, or donations, but the diagnostic tools remain accessible without payment.

Does it work on mobile devices?

Most tests work on mobile phones and tablets running modern browsers. The dead pixel test, audio test, and click speed test all work well on mobile devices. Keyboard testing works best with a physical keyboard, so it is more useful on desktop or laptop. The controller test requires Chrome for Android for the best Gamepad API support. For the most accurate results on any test, we recommend using a desktop or laptop browser.

Is my data private and secure?

Yes, tests run locally in your browser. We do not upload raw test data, keystrokes, mouse movement paths, microphone audio, camera video, or controller identifiers. We use Vercel Analytics and Google Analytics 4 for aggregate product metrics such as page views, test starts, test completions, and outbound clicks.
